“…BENTIX and BO2A. AMBI (AZTI Marine Biotic Index) based on the study of [39], which considers five ecological groups ranging from sensitive species (EGI) to first-order opportunistic species (EGV) [43]. BENTIX considers only two groups: sensitive (GS) and tolerant species (GT), which correspond to ecological groups I and II, and to ecological groups III to V of the AMBI, respectively [44] [45].…”

The present study analyses the spatio-temporal variability of the macrozoobenthos from the intertidal zone of the Kneiss Islands (Gulf of Gabès, Tunisia). Samples were collected once from 34 stations, while seasonal variations were studied by sampling four times at 12 stations over the period 2013-2014. A total of 159 macrobenthos taxa associated with intertidal Zostera noltei beds are identified from the 34 stations, with a taxonomic dominance of crustaceans (32%), molluscs (29%) and annelids (27%). Abundance varies from 9244 to 36,844 ind·m −2 with a mean value of 14,346 ind·m −2 . Analysis of the trophic structure shows that the majority of stations are strongly represented by carnivores (41%), followed by the non-selective deposit feeders (16%). Cluster analysis and multidimensional scaling allow identification of three main benthic assemblages based on species abundance, corresponding to different sediment types and organic matter contents. The seasonal variability in abundance, diversity and community structure is mainly due to spring and summer recruitment. The biotic indices (i.e. AMBI, BO2A and BENTIX) show that the intertidal area of Kneiss Islands exhibits a good ecological status.

“…with EG I being the disturbance-sensitive species, EG II the disturbance-indifferent species, EG III the disturbancetolerant species, EG IV the second-order opportunistic species and EGV the first-order opportunistic species (Grall & Glémarec, 1997;Borja et al 2000). Calculation of the AMBI index was made with the use of AMBI_v5.0_2012 (AZTITecnalia, www.azti.es) software.…”

“…A similar rating of the disturbance level was obtained on the basis of the diversity indices (H′ and S). However, a second analysis of the M-AMBI index was done with a new classification of species, where the invasive species were re-classified in the ecology group V (EG V) or the first-order opportunistic species (Grall & Glémarec, 1997;Borja et al 2000) (e.g., Marenzelleria spp.). The results of the second analysis modified the mixed and sandy sediments to 'Moderate EcoQS', and the muddy habitats to 'Poor EcoQS' (Figure 17.5).…”
